Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Miconazole inhibits fungal cytochrome P450 14α-demethylase (CYP51), thereby blocking the conversion of lanosterol to ergosterol, an essential component of the fungal cell membrane. This leads to increased membrane permeability and fungal cell death.
Nystatin binds to ergosterol in fungal cell membranes, forming pores that disrupt membrane integrity and cause leakage of intracellular contents, leading to fungal cell death.
Intravaginal: 1 applicatorful (100 mg) at bedtime for 3 consecutive nights.
1 tablet (nystatin 100,000 units) orally three times daily after meals. Each tablet should be allowed to dissolve slowly in the mouth.

Terminal elimination half-life is 20-25 hours (intravaginal administration). This long half-life supports a 3-day dosing regimen, maintaining therapeutic concentrations.
Plasma half-life is not measurable due to negligible systemic absorption. Topical or oral administration results in local action only; no systemic half-life is clinically relevant.
Renal: approximately 10-20% as unchanged drug; fecal: >50% as metabolites; biliary: minor route. The majority is eliminated via feces as metabolites, reflecting hepatic metabolism and biliary excretion.
Nystatin is not absorbed from the gastrointestinal tract, intact skin, or mucous membranes. After oral administration, it is excreted almost entirely unchanged in feces (over 99%). Minimal renal excretion occurs (less than 1%).
